I began building the sled with the large platform. And there are a couple details worth mentioning.

The first is the material. We used phenolic-faced ^l/i plywood for the platform. This tough plywood has a smooth surface that's great for jigs. (For more on this, turn to page 10.) But you can just as easily use standard V2" plywood if you wish.

Dado. The other detail that I want to talk about is a dado that runs across the platform. It's sized to hold a backing strip for the

workpiece. It's a good idea to cut this dado while the platform is still square. Once the dado is cut, you can shape the platform (Figure 1).

After shaping the platform, I took it over to the router table and routed a chamfer on all the top edges — except for the long side that faces the router bit.

Miter Bar. The sled is guided by a bar that fits in the miter gauge slot of the router table. To prevent the platform from contacting a router bit, I positioned the edge of the

platform 1" away from the center-point of the bit and parallel to the miter slot. A strip of carpet tape will temporarily fix the position of the miter bar so you can screw it in place. In Figure 2, you can see how I used the edge of the table and fence to position the platform.
